With the end of the year approaching and Boxing's Best airing, it's as good a time as any to take a look back at a stacked year of fights on HBO. HBO Boxing Insiders made their selections for the top everything from this year's HBO fights. Next up, HBO Trainer of the Year.

Abel Sanchez has overseen the emerging superstardom of Gennady Golovkin, but as effective as he has been in molding his charge into the fan-friendly fighter we see today, the raw material with which he had to work was of the highest quality. Adonis Stevenson, on the other hand, was more of a diamond in the rough. The great Emanuel Steward barely had time to begin polishing that diamond before his untimely passing; Hill, Steward's nephew, has taken over the work his uncle started and has helped create a versatile and fan-friendly star in the making.

Eric Raskin: Javan "Sugar" Hill

In a year in which the most recognizable trainers with deep stables—Freddie Roach, Robert Garcia, Virgil Hunter—had too many ups and downs to keep track of, Hill is my pick because of what Adonis Stevenson achieved. Also, by picking Hill, I'm giving a bit of a posthumous award to the best trainer of recent decades, Emanuel Steward, who worked with Stevenson and Hill prior to his untimely passing in 2012.

Nat Gottlieb: Robert Garcia.

He's the hottest young trainer in the business, and he had a great year. Among the A-list of fighters he worked with this year were Nonito Donaire, Evgeny Gradovich, Brandon Rios, and his own younger brother, Mikey.

Tim Smith: Javan "Sugar'' Hill

The trainer for Adonis Stevenson set himself apart in 2013. Hill, the nephew of the late Emanuel Steward, took over training Stevenson after Steward passed away. Hill built on the foundation that Steward established and has set Stevenson on a path for greatness.

Hamilton Nolan: Abel Sanchez

There are plenty of good trainers and plenty of good fighters. But since no trainer this year can really claim two fighters who had incredible years, I have to go with the trainer whose one fighter--Golovkin--had the most incredible year. Sanchez is relaxed, cerebral, and knows what he's doing. Golovkin is lucky to have him.

Michael Gluckstadt: Freddie Roach

Just because someone's the best player year after year, doesn't mean you stop giving them the MVP. Roach continued to ply his trade as the best trainer in the game, overseeing the emergence of Ruslan Provodnikov, the resurgence of Miguel Cotto, and the return of Manny Pacquiao, among other feats. And the former boxer also showed he can still take a blow -- in this case, a kick to the stomach from Alex Ariza.
